This study is a sad and sick glimpse into human nature. Mentioned is Hal Herzog's book "Some We Love, Some We Hate, Some We Eat," mentioned in the article. Haven't read it but sounds interesting and it's now on my long list of books to read.
College student's turtle project takes dark twist - Yahoo! News: CLEMSON, S.C. (AP) — Clemson University student Nathan Weaver set out to determine how to help turtles cross the road. He ended up getting a glimpse into the dark souls of some humans.
Weaver put a realistic rubber turtle in the middle of a lane on a busy road near campus. Then he got out of the way and watched over the next hour as seven drivers swerved and deliberately ran over the animal. Several more apparently tried to hit it but missed.
